1. An apparatus comprising:
at least one processor; and
at least one non-transitory memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least:
identify, by a user equipment of a communication network, downlink control information,
wherein the downlink control information indicating that at least one hybrid automatic repeat request-acknowledgment codebook scheduled earlier for transmission needs to be re-transmitted in a physical uplink control channel occasion indicated by the downlink control information, and
wherein the downlink control information identifying which at least one hybrid automatic repeat request-acknowledgment codebook scheduled earlier for transmission needs to be re-transmitted in the physical uplink control channel occasion; and
based on the downlink control information, prepare the physical uplink control channel for re-transmitting the identified at least one hybrid automatic repeat request-acknowledgment codebook in the physical uplink control channel occasion.
